Descriptions

This study had two purposes: to determine solid waste
management needs of residents and organizations of the San
Xavier District Indian reservation near Tucson, Arizona;
and to develop a solid waste management plan to be
recommended to the San Xavier District Tribal Council.
A solid waste generation study compared the daily per
capita solid waste generated over one week by 25 Indian
households, 15 Adult non-Indian households and 15 Family-
Adult non-Indian households on the district. An analysis
of variance showed that the differences in daily per capita
solid waste generation among the three groups were not
statistically significant at the .05 level, and a t-test
showed that differences between the Indian residents and
the non-Indian residents considered as one group were not
statistically significant at the .05 level. The overall
daily per capita solid waste generated by all groups, 1.71
lbs/day, was less than half of the national average of 3.5
lbs/day. The Adult non-Indian households had the highest
daily per capita solid waste generation (1.96 lbs), while
the Indian and the Family-Adult non-Indian households
generated a similar amount of solid waste daily per person
(1.67 and 1.64 lbs respectively).
Four alternative solid waste management proposals were
developed: (1) a tribal-operated solid waste management and
disposal service serving all residents and most organizations
on the San Xavier district and trucking solid wastes
off the reservation; (2) the same as Alternative One except
that disposal would be in an 8.24 acre landfill to be
constructed by the tribe on the district; (3) contracting
waste pickup and disposal to an outside waste management
company; and (4) the same as Alternative One except that
commercial organizations on the district would not be
served.
Evaluation of the four proposals showed that
Alternative One best fulfilled the objectives of the san
Xavier District Tribal Council, and that alternative was
chosen for recommendation to the San Xavier District Tribal
Council. It was also recommended that a recycling proposal
by U.S. Recycling Industries be accepted.
